Rooted to the bottom of the Premier League table with just 13 points, 10 adrift of safety, Villa fans were hoping for some transfer activity before the transfer window slammed shut on Monday night.
Garde is reportedly ready to review his position as manager at the end of the season after missing out on at least five targets.
Only bottom six club not to make a signing
Villa were the only club in the Premier League’s bottom six not to bring in a new signing.
Sky Sports pundit Merson played over 100 times for the Villains scoring 18 goals and still cares about the club.
He was angered by their lack of activity and explained why they should have rivalled another of his old clubs Middlesbrough for the signing of striker Jordan Rhodes who left Blackburn Rovers for £11 million.
All Rhodes lead to relegation
When asked 'What now for your old club?' when appearing as a guest on Sky Sports' deadline day coverage, Merson did not mince his words.
"Relegation," he told Sky Sports News.
"It's virtually saying 'We're going to get relegated'. If you're not buying any players and you keep on doing the same things you're going to get the same results.
"I'd find it hard for him (Garde) to hang around.
"You'd have thought they'd have gone in for someone like Jordan Rhodes, you know have a go.
"He'll score you goals and if you do (still) get relegated you know he'll get you 20 goals in the Championship so you're sort of half building for the Championship but still having a go in the Premier League.
"But it looks like they're going to go out without even a fight now, which is a shame."
Garde takes his Villa side to high-flying West Ham this evening with speculation now swirling over his future.
